A reason the Japanese government accepted a new constitution after World War II was that the "new constitution" was imposed by the "United States military government".

Explanation:

After World War II, the Japanese state was in a great need of social and political rehabilitation. Thus, in response to this need, the allied powers, viz. the United States, the Soviet Union, Great Britain and the Republic of China decided to introduce major reforms in Japan in order to bring in social, economic and political stability. This led to the drafting and implementation of a revised constitution of Japan. It is said to be imposed by the US military government because the constitution was implemented under the leadership of the General of the US Army, Douglas Macarthur.
